Girl group 4Minute released the practice room version of their "Crazy" dance video.

4Minute held their last stage of "Crazy" on Sunday night and released a surprise bonus video clip on their YouTube channel.

In the video, 4Minute is in casual outfits for practice while giving a charismatic performance in their practice room. The members looked comfortable as they remembered to smile for the camera in between the dances, adding to the fun of their performance.

The video was also taken on one take and the fans are able to see every dance move in detail.
